摘要： Transferring a mobile node from one ASN-GVV ( anchor access sen ice network gateway ) to another ASN-GW is referred to as a hand-over. To facilitate transfer of data for the hand-over, a GRE (generic routing encapsulation) tunnel is established between the two GWs Traffic through the GRE tunnel arriving at a line card of an ASN-GW is redirected from the arrival line card to the one line card that contains information for the mobile node The redirection is based on traversal of one or more tables, on the line cards These tables are indexed according to GRF, keys corresponding to the mobile nodes Therefore, the appropriate line card for the traffic can be identified quickly and efficiently using a distributed forwarding aiding plane with minimal provisioning overhead, resulting in lower latency during the hand-over
